Message

Pawel Laszczak July 13, 2020, 10:05 a.m. UTC

Series introduce some improvements to drd.c, drd.h and core.c files of 
cdns3 driver.

Except for the first (1/9) patch that removes not needed function,
the rest patches make improvements suggested by Dan Carpenter
during reviewing CDNSP driver.
CDNSP is the next Cadence USBSSP  driver which will be upstreamed.
The DRD part is similar for both CDNS3 and CDNSP and Greg suggested
to merge the similar part of DRD code. As first step I want to merge 
some improvements.

Changes for v2:
 - Change patch titles as sugested by Peter Chen.
 - Remove typos in patch 5 and patch 7.
 - Add reviewed-by Peter Chen tag [Patch 1, patch 8 and Patch 9].
